What are glandless transformer oil pumps used for in power transformers?

Glandless transformer oil pumps are used for circulating transformer oil in power transformers. These pumps are designed to operate without traditional packing glands, reducing maintenance needs and preventing oil leaks. Their efficient design allows for consistent oil flow, which is crucial for cooling and insulating the transformer. By maintaining optimal oil circulation, glandless transformer oil pumps enhance the reliability and longevity of power transformers.
